It is recognized within the industry that most data centers are not energy efficient. Traditional data center designs do not fully address optimizing the data center. While data center managers struggle with uptime and reliability, business executives are looking for ways to reduce capital and operational expenses to improve the bottom line. Green initiatives are also in place to not only save money but to be environmentally responsible. New green data center designs (based on hot and cold air containment) have started to become more popular. Containment strategies and air flow optimization are recognized as a way to achieve both technical and business objectives. By separating hot and cold air within the data center, capital and operational expenses can be reduced for the business and a more stable and predictable environment can be achieved for the IT organization.
